AUGUST P. LIGHTHILL, OF BOSTON, MASSACHUSETTS.

ATOMIZER.

SPECIFICATION forming part of Letters Patent No. 365265, dated June 21, 1887.

Seial No. 188.990. (No model.)

To all whmn, it may conccrn:

Be it known that I, AUGUs'r P. LIGHTHILL, of Boston, in the county of Suffolk and State of Massaehusctts, have invented certain new and useful I mprovements in Atomizers or Nebulizcrs, of which the following is a speciii catiou.

My invention relates to what are commonly known as atomizers, or those contrivanccs employed to vaporize liquids,such as antiseptic renedies or medicines of any character which are applied by t'ansforming the liquid into a vapor or fog.

It is the object of my invention to imp'ove the means enployed to effect au absoluteatonization or nebulizationof liquids, so that they can be inhaled and drar into the utnost recesses or eavities ofthe lungs or be forced into any part of the human system where air or other gas could be introduced. or be evenly and thoroughly distributed in the atmosphere of a sick chamber or any apartment which it may be desired to funigate.

To the foregoingends my invention consists in the improvemcnts hereinafter described, and subseqnently pointed out in the claims.

In thedrawings hereto annexed, and forming a part of this specification, Figure 1 represents a side elevation of myinproved atomizer. Fig. 2 represents a vertical section through the top and. cover of the receptaele and the inlet and discharge tubes. Fig. 3 represents a vertical section of the air and liquid tubes at and a short distance beyond theirjetorifiees. Fig. arepresentsa side elevation ofa modified Construction of a deviee enbodying ny improvements.

The same letters of reference indicate the same parts in all the figures.

In carrying out my invention, I provide a reeeptacle of any suit-able character, preferably a glass bottle orjar of the form and character represented in Fig. 1, into which the liquid to be atomized is poured. Said receptaele is provided witha cover, a, suitably constructed to receive therethrongh and support therein the air-inlet tube I and discharge-tube,

`c, as usualin this class of devices,except in the respeets hereinafter noted.

I form the liquid-tube d as an integral part .of the air-tube b forming the hollow or bore of the forner straighttherethrough, while the bore or hollow ol'the latter is formed straightto apoint near thejet-orifice where it is turned at a right angle therelo, and to the bore of the the liquid-tube, as clearly represented in Fig. 3 of the drawings. By this Construction I an enabled to construet the liquid and air tubes ofan atonizer so that they constitute substantially asinglestraight stcu and can be readily introduced through the neck of the snallestsized bottles. I am also enabled bythis con struction to insu re at all times a proper relationship of thejet-orifices to each other.

As shown in Fig. 2 of the drawings, I sur round the inlet-tube b at the point where it passes through the top or cover` of the jar or bottle With a rubber or othersimilarpacking, e, which,while fitti ng closely around said tube, permits it to be adjusted ve'ticallytherein. It is to be noticed, also, thatsaid tube b is eccentrically arrangedin said cover or top-that is, it passes through the cover at a point to the side ofthe center thereof.

The neck of the bottle is externally screwt-hreaded at its upper end, and adapted to be received within the internally=serew threaded cap, by which Construction the cap may not only he turned on the bottle-neck, but be raised and lowered thereon as well.

In the Construction represented in Fig. l I have shown a bulb, f, as a means for forcing air through tube b, though any other means for the same purpose might be employed.

By the contrivance shown and described the atomized liquid is forced against the side of the jar, and thus broken into athin cloud, or perfectly atomized or nebulized and rendered capable as it issues from the dischar'getube as a cloud of smoke of being inhaled or drawn into the lungs, or introduced into any part of the human system where it is possible for air or other gas to be forced.

\Vheu it is desired to have the atomized liquid impinge more directly against the side of the receptacle, and thus insure the breaking of the liquid into the finest possible particles and secure perfect nebulization, the cover ofthe receptaele may be rotated or turned, so as to bring the jet-nozzles nearer the side of the reeeptacle; or the same result may be aeconpl'shed where the sides of the Vessel are augu- ICO lar or tapering in form by adj usting the tubes vertically inthe cover of the receptaelc, thus bringing thej et-zozzles nearer to the contracted sides of the bottle or jar.

In Fig. 4 I have show-n a somewhat different Construction and arrangement of, parts and illnstration of the manner ofadjusting such dilferently-organized parts in different positions, in order to nebulize liquids to a greater or less extent to meet the needs of particular cases, employing in this instance air and liquid tubes arranged with respect to each other as is common in atomizers and located within a 'funnel-shaped glass receptacle, the opening in the smaller end of which affords a disehargeorifice for the nebulized liquid. In this arrangement the atomizer is supported on an arm, g, pivoted at h to the side of the support z'. Said arm is properly guided and supported so as to maintain the atomizerin proper position, its hinged connection with the frame providing for adjusting the atomizer so as to cause the atomized fluid. to impinge more or less direct against the sides of the reeeptaele.

When the atomizer is in the position represented in said last-mentioned figure, the spray v'ill bethrown against the side of the vessel near the mouth ofthe fu nnel; but ifdirected upward by rocking arm g baekward on its pivot it will come in more nearlyimmediate contact with the side of the receptacle, and as a consequence With greater force.

Having thus described my invention, I claim- 1. In an atomizer constructed as a single and substantially straight stem, the liquidtube formed below or beyond the air-tube, and the jet-orifices eonstructed at a point between the ends of the said substantially straight stem, Whereby the stem comprising the tubes may be inserted and operated in a small Vessel or vial, or Vessel or vial having a small neck, as and for the purposes set forth. i

2. In an aiomizer'or nebulizer, the eonbination ofa liquid-holding vessel or recep taele and cap or stopperto which the inlet or outlet tubes are attached, with the liquid tube and'air-tube constructed in a substan tially straight line with the jet-orifices, which are located at a point between the ends of said 0 substantially straight stem, as set forth.

3. In an atomizer, the combination, with the vessel or reeeptacle, of the liquid and air tubes arranged with respect to the vessel to cause the atomized fluid to impinge against the sides thereof, and means, substantially as hereinbe' fore described, for adj usting the jet-orifiees of the tubes to bring the same nearer to or remove then farther from the side of the vcssel,

whereby the atomizcd liquid may be broken Go into a cloud and the lightness or thinness of such cloud or nebulze may be varied, as set forth.

4. In an atomizer, the eonbination, with the reeeptaele and its rotary cover, ofthe liquid and air tubes construeted as a single and substantially straight stem, the liquid-tube being formed below or beyond the air-tube, and thejet-orifices being constructed at a point between the ends of said substantially straight? i stem, said stern being supported eceentrieally in and by said rotary cover, and means, substantially as h'e'einbefore described, whereby the cover may be rotated on the receptacle to bring the atonizing-point of the tubes nearer 7 5 to or remove it farther from the side of the vessel, as set forth.

In testimony whereofl have signed my name to this specifieation, in the presence of two subscribing witnesses, this 12th day of January, 1886.
